Mandevilla Plant Named &#39;KLEMS16028&#39;

ABSTRACT

A new mandevilla plant particularly distinguished by pink flowers and vigorous upright growth, is disclosed.

Genus and species: Mandevilla sanderi.

Variety denomination: ‘KLEMS16028’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of mandevilla, botanically known as Mandevilla sanderi and hereinafter referred to by the variety name ‘KLEMS16028’. ‘KLEMS16028’ originated from a controlled cross in February 2010 in Cobbitty, New South Wales, Australia between the proprietary female mandevilla variety ‘X08.12.6’ (unpatented) and the proprietary male mandevilla variety ‘No.2’ (unpatented).

Seeds from the controlled cross were obtained and sown and plants were grown for evaluation. A single plant was selected in February 2012 and subsequently named ‘KLEMS16028’. In February 2012 ‘KLEMS16028’ was first vegetatively propagated in Cobbitty, New South Wales, Australia by vegetative stem cuttings. ‘KLEMS16028’ was found to reproduce true to type in successive generations of asexual propagation via vegetative cuttings in Stuttgart, Germany, Cobbity, New South Wales, Australia, Stuttgart, Germany, and Nairobi, Kenya.

SUMMARY

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Cobbitty, New South Wales, Australia.

-   -   1. Pink flowers; and     -   2. Vigorous upright growth.

DESCRIPTION OF THE PHOTOGRAPH

This new mandevilla plant is illustrated by the accompanying photograph which shows an overall view of the plant. The photograph is of an approximately 8 months-old plant grown in Stuttgart, Germany, under greenhouse conditions, in July 2014. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘KLEMS16028’. The data which define these characteristics were collected from asexual reproductions carried out in Cobbitty, New South Wales, Australia. Data was collected on 16 week old plants grown in Cobbitty, New South Wales, Australia in a greenhouse between October (2016) and January (2017). Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 5^(th) edition (2007).
